DOOR HOLDER necticut Application- May 15, 1952; Serial No'. 287,930

6 Claims". l.

This invention relates to a door holder and more particularly to a device for holding a door in its opened position.

An object of the present invention is to provide an improved door holder having novel advantages over such related devicesas have heretofore been produced and which isl easy to manufacture, more edcient in. its operation and durable.

Further objects and advantages of this invention will be more clearly understood fromthe following description and from they accompanying drawings in which:

Fig. 1 is a bottom view of a door and casing with my improved door holder' installed thereon.

Fig. 2 is a sectional plan View, on line2-2 of Fig. 3, showing the device embodying my present invention in latched condition.

Fig. 3 is a side view of said device.

Fig. 4 is a sectional end view on line 4 4 of Fig. 3.

Fig. 5 is a side view of said device, partly in central vertical section. Y

Fig. 6 is a sectional end View on line -Bof of Fig. 5.

Fig. '7 is an end view of the supporting member oi said device.

Fig. 8 is a side view of said supporting member.

Fig, 9 is a side view showing the said device in unlatched condtion.

In the embodiment which is illustrated in the drawings, the numeral ii denotes the casing of a door and 5 denotes the door which is hinged to said casing in the conventional manner.

My improved device includes a mounting plate l that is adapted to be secured to the door casing and a supporting sleeve 8 which has an upright portion S by which the said sleeve is pivotally'mounted upon the plate I and preferably secured thereto by means of a retaining washer It.

A slide bar Ii extends longitudinally through the said sleeve fi and is slidable therein. This bar has, adjacent its end portion, a stop collar I2 which abuts a` holding pin i3 that extends transversely through the said slide bar and is received in longitudinal slots ill-*Id in the forward portion of the supporting sleeve. A compression spring I5 is mounted over the end portion of the said slide bar, between the said stop collar l2 and an anchoring nut i6 which is threaded to the slide bar and is adjustable thereon for varying the tension of the said spring I5 against the stop collar.

The said supporting sleeve also carries'thereon a latch member Il which is disposed adjacent the bottom of the supporting sleeve and has up*- right side portions Ill- I8 by means of which it is pivotall'y mounted at I9 upon the upright portion 9. This latch member has, at its front end, upright inverted cam-shaped portions 2%-20 which areV disposed at the opposite sides of the forward portion of the supporting. sleeve 8; the said portions each having a cam surface 2'I at the forward edges thereof and a similar cam surface 22 at the rear edges.

The slide bar II is provided with a latching pin 23 which extends transversely therethrough, projects from the opposite sides thereof and has a roller sleeve 24 rotatable on each end thereof for engaging the cam edges ZI and 22 of the latching member. This latching pin 23 is adapted to be also received within the longitudinal slots I4.

Upon the rear portion 25 of the supporting sleeve there is slidably mounted a sleeve 26 which is urged in the direction of the latch member I1 by means of a spring 2 that is disposed between the said sleeve and an anchoring nut 28 that is threaded to the portion 25 for adjusting the tension of the said spring 21.

The rear end of the bar I I is pivotally secured to a suitable bracket by means of which the said device may be attached to the door as shown.

The operation of my improved door holder is as follows:

The latch member l'l is biased into its latching position by means of the spring 2l which forces the sleeve 2E against the latch and rocks it against they bottom of the supporting member 8. Compression of the spring 2l may be adjusted by thel nut 28 so as to regulate the force applied to the latching member.

When the device is in unlatched position, as shown in Fig. 9; the collar l2, which is under the tension of the spring I5, will abut the stop pin I3 as shown. The force exerted by the said spring I5 may be regulated by the anchoring nut I6 which is adjustable on the threaded portion of the bar II..

When the door is opened or closed normally, the bar II will simply slide through the supporting member `8v without any effect on the door. When it is desired to have the door held in opened position by my improved device, the said door is'swung towards the position shown in Fig. 1. This will cause the bar Ii to be pulled and the pin 23 to engage the cam surface 2| and thereby rock the latch member on the pivot I9, against the forceof the spring 21. The said pin will then .move into its latched position wherein it will be in engagement with the cam surface 22, as clearly shown in Fig. 5. When in this position, the pin I3 will have entered the slot I4 and the collar I2 will engage the end of the supporting member 'I so as to prevent movement of the door in either direction.

Should the door be forcibly swung so that the bar II will be pulled beyond its normal latching position, the further movement of the door will be checked by means of the compression spring I5 since the collar I2 will abut the end of the supporting member 8 and then slide on the .bar Il against the force of the said spring. During the said checking movement of the bar II, the pins I3 and 23 will move with the bar I I and in the slot I4. If an excessivelystrong push is applied to the swinging of the door, the pin I3 will engage the cam surface 2| and thereby swing the latch member I'l downwardly and apply the tension of the spring 2?, in addition to that of the spring I5, in further checking the movement of the door.

It will be readily understood that the latching tension which is applied by the latch member' I1 may be varied entirely by the adjustment of the nut 23 and that the checking resistance of the device is adjusted entirely by the nut IB so that independent adjustments of the device for latching and checking the movement of thev door may be readily made to provide smoothness and efficiency of operation.

I claim:

l. En a door-holding device, 'the combination of a. supporting member, a latch member pivotally mounted upon said supporting member, adjustable spring means carried by said supporting member for variably forcing said latch member towards iatching position, a rod slidable on said supporting member, a projection on said rod engageable with said latch member, separate spring means cooperating with said supporting member for checking movement of the rod beyond its normal latching position, and cooperating means on said latch member and rod operating against the force of the first spring member for additionally checking the movement of the rod beyond its latching position.
